Lichess-bot Python Bridge

This engine implements the UCI protocol and can be used as a bot on Lichess. You can use the python bridge between Lichess Bot API and the engine: https://github.com/ShailChoksi/lichess-bot.

To run it as a bot you'll need to produce a python executable. PyInstaller can produce it by running the following command:

python3 -m PyInstaller main.py

This creates a build and dist folder. The dist folder contains the main executable in a folder called main. All the files inside main need to be copied over to /lichess-bot/engines for it to work. You can checkout /lichess for further lichess setup.
